tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference heing had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a l5 part of this specification.

lily invention. relates to a discharging de vice :for firearms, in which it is possible to pull the previously locked trigger only in the. correct slanting position or elevation of the weapon. My device differs from welllmown devices for the same purpose in that it is exceedingly simple it being apparently' Aimpossible for the device to break down lor become unusable in consequence of a fall 25 or hlow with the weapon.

Some illustrative embodiments of my inventionare represented hy wey of e ample 1n 'the accompanying drawing, wherein r Figure i is a side elevation showing one f 3*) orin of the device, Fig. 2 a. section in 'the pla-ne fir-l in Fig. 1, and 3 a, detail;

Figs. and 5 show details ci two modified forms..

Referring firstly to i to 3, ar-

range reY-Joluhly. on a pin secured in the butt c or" the 1lieapon a disk j" having a scale g on a portion-oi its lateral ineen At a corresponding part of the butt i provide an arc-shaped slit, which may he covered 'oy a 40 transparent plate, so that the scale .is visible from the outside. The disk f preferably has an enlarged rim j" in which a recess f2 is provided. The rim f of disk f is clasped hy pro- Y jections 71. of a weight or pendulum hin which a is journaled a small pinion s adapted to he rotated from the outsideland meshing with gear-teeth lu on the periphery oi' the disk. The periphery of the dislt is preferably roughened so that el'astically mounted brake- O blocks e, for preventin c idisplaced unintentional y relatively to the the weight being disk, andxarranged inside the weight h or the like, can secure a ood hold on the pen index h2 provided 'on weicht 7. is located over the scale g.

Opposite disk f I arrange a locking rod c movable longitudinally in guides m, n and able to coact with the trigger p hy means of a movable member 0. This form of m device is used and operates as follows: hen ieldring at 1500 meters, for example, the company or squad will first adjust the scale g in all the weapons by turning pinion 3 so that the index h2 registers with the point of the scale corresponding to this distance. As soon as the weapon is moved into that slanting position which is requisite for the distance 1n question, the recess will be opposite rod It', which now allows the trigger to be pulled, the tree end of the rod entering into said recess. After the weapon has heen discharged rod 7c is automatically returned into its normal position by a spring r coacting with it.

Referring to Fig. t, the disk and Weight shown in Figs. 1 to 3 forni a pendulum: f3 revoluble around pivot b and having on its bottom side a recess f2. nto this' there can enter an adjustable projection k1 of a lever kg whiciiis. fulcrurned at 7c3 and coacts with its erin with rod k, so that when the trigot the weapon is actuated lever k2 is moved 'upwardiy in the direction of the arrow and the projection icl enters into the recess when the Weapon is held in the cor rect position. The projection .h1 is displaceable, for example, in a siot k of lever 7a2 and can he secured to the latter by a screw, which can he introduced from the side or from helow into the carrier of the projection, in order telecable to adjust the projection to dierent distances of target. rhe scale of distances is preferably provided on lever The illustrative embodiment represented in Fig. .5 is ay reversal of that represented in Figs. l to 3 inasmuch as I provide the recess 'f2 in the widened end le of rod lc, and I arrange o posite it on the periphery of disk f a projection f4, which enters into recess f2, when the trigger of the weapon is actuated and rod c is moved backward, in the event of the Weapon beingpositioned correctly corresponding to the adjustment at any time of Weight l. In a device of the character described for preventing the discharging of a tire-arm except when it is in a redetermined position, the combination with the trigger of a rod adapted to coact with the trigger, a pendulum and a Weight adjustably mounted on said pendulum, said pendulum normally locking said rod and having a recess alloiv ing-,the entering of said rod and thereby the pulling of the trigger when the firearm is ynormally locking said rod and ad-apted to release the same in a predetermined position of the fire-arm, a Weight adjustably mounted on said pendulum, and a pinion journaled in said Weight and meshing With said gear teeth.

3. In a device of the character described `\for preventing the discharging of a fire-arm except When it is in a predetermined angular position, the combination with the trigger of a rod adapted to coact with the trigger, a pendulum normally locking said rod and adapted to release 'the same in a predetermined posit-ion of the tire-arm, a Weight adjustably mounted on said pendulum, and spring-pressed means automatically fixing said Weight relatively to said pendulum.

4..In a device of the character described for preventing the discharging of a rearm except when it is in a predetermined angular position, the combination with the trigger of a rod adapted to coact with the trigger, a pendulum normally locking said rod and adapted to release the same in a predetermined position of the tire-arm and having a scale on the rim thereof, and a Weight adjustably mounted on said pendulum and having a pointer movable over said scale.v l

In testimony that I claim the foregoing as my invention, I have signed niy'name in presence of two subscribing Witnesses.
